I have updated the zip file to 1.1 to reflect the query optimizations by rangersfan. You can find the newest version, including instructions on updating the old version, here:

VT, I'm working on that most ignored script. I'm sorry I had quoted that query incorrectly-- there is no field "user" in the table "user"... the query should be:
select username,ignorelist from user where ignorelist !="";
I'm working on the file so it will give the results you want.. will post in a bit.
